METHOD FOR MANUFACTURING ANODIZED POROUS ALUMINA AND ANODIZED POROUS ALUMINA MANUFACTURED BY THE METHOD

摘要

PROBLEM TO BE SOLVED: To surely manufacture anodized porous alumina having such a desired form that micro pores are arrayed in high regularity by easily controlling anodization conditions and maintaining optimized anodization conditions with satisfactory reproducibility even to a sample having a large area.

SOLUTION: In a method for manufacturing the anodized porus alumina, when an aluminum material is anodized, anodization in a first stage is performed, and then anodization in and after a second stage is performed by changing at least one of an anodization voltage and an electrolyte concentration. The anodized porous alumina manufactured by the method is also provided.
